If a person wanted to set up a 4' X 5' flowering room, using a 1000W HPS (w/ cooltube) would they be able to bring in "fresh" air from underneath the house, from the 2ft crawlspace, through the cool tube, and up to the attic? The reason I ask is b/c the air under most houses is kinda stale, but it is very cool, just wondering if you start moving the air if it would start becoming more "fresh". There is also concern with a little bit of moisture from under there, which they are trying to get fixed at the moment. This person is also considering doing it with this fan from HD
